Constructor Details

SynthListUI

             public SynthListUI()
            

构造一个SynthListUI。

Method Details

createUI

             public static ComponentUI createUI(JComponent list)
            

为给定的组件创建一个新的UI对象。

参数:

list - 要为其创建UI对象的组件

返回:

UI对象

update

             public void update(Graphics g, JComponent c)
            

通知此UI代理重新绘制指定的组件。此方法绘制组件背景，然后调用BasicListUI.paint(java.awt.Graphics, javax.swing.JComponent)方法。

一般来说，子类不需要覆盖此方法。所有外观渲染代码应位于paint方法中。

覆盖:

update 在类 ComponentUI中

参数:

g - 用于绘制的Graphics对象

c - 正在绘制的组件

参见:

• BasicListUI.paint(java.awt.Graphics, javax.swing.JComponent)

paintBorder

             public void paintBorder(SynthContext context, Graphics g, int x, int y, int w, int h)
            

绘制边框。

指定者:

paintBorder 在接口 SynthUI中

参数:

context - 组件上下文

g - 要绘制的Graphics

x - X坐标

y - Y坐标

w - 边框宽度

h - 边框高度

propertyChange

             public void propertyChange(PropertyChangeEvent e)
            

当绑定属性更改时调用此方法。

指定者:

propertyChange 在接口 PropertyChangeListener中

参数:

e - 描述事件源和已更改属性的PropertyChangeEvent对象

getContext

             public SynthContext getContext(JComponent c)
            

返回指定组件的上下文。

指定者:

getContext 在接口 SynthUI中

参数:

c - 请求SynthContext的组件

返回:

描述组件的SynthContext
